[vlc-devel] [PATCH] qt: force signals from the player callbacks to be emmited from a queued connection.

[Pierre Lamot]

  callbacks are called with the player locked, if the callback commes from Qt thread,
  the signal emitted by Qt may be handled within the same thread directly and ask for
  the player lock again.
